When using reverse osmosis equipment, it is necessary to calculate a parameter, which is the pure water recovery rate. This not only divides the quality of the equipment, but also provides a good analysis of water quality. So, what is the recovery rate of this type of equipment? Below, the editor will teach you calculation methods.

The pure water recovery rate of reverse osmosis equipment depends on water resources, and the proportion of water production rate varies. Generally, the proportion of small pure water machines used in households is 3:1, the proportion of reverse osmosis system software used in small and medium-sized industrial production is 1:1, and the proportion of large and medium-sized system software is 0.3:0.7. With the improvement of sewage treatment technology, the sewage of reverse osmosis system software can be solved and applied through reuse system software. Therefore, the ratio of sewage to pure water is not certain, and even zero discharge can be achieved. However, the cost is relatively high, and the service life of reverse osmosis system software is undoubtedly not long. Therefore, it is generally not necessary to achieve zero discharge in general. The professional term is called recovery rate, and different recovery rates can be achieved based on the number of reverse osmosis membranes and their sorting methods.

Calculation method for pure water recovery rate: How to calculate the recovery rate for multi-level reverse osmosis equipment, and meet different requirements based on different situations. For first stage reverse osmosis, the first stage recovery rate (r1) r1=first stage water production rate/first stage inlet flow rate 100%; The recovery rate of the second stage reverse osmosis is r2=second stage water production rate/second stage inlet water flow rate of 100%. The recovery rate of secondary reverse osmosis is not obtained by multiplying the software recovery rates of two levels of reverse osmosis systems. The concentrated water in the second stage reverse osmosis system software is not discharged, but instead flows back to the inlet of the first stage reverse osmosis. Therefore, the recycling and utilization of multi-level reverse osmosis equipment should be calculated according to the following specifications: system software recovery rate=total water production rate/total inflow rate of 100%.

In general, in order to improve the recovery rate of reverse osmosis equipment in production and manufacturing, membrane components are connected in series. However, if there are many membrane components in the system software, they cannot all be connected in series. If this is done, the water output of the first membrane will be very large, and the working pressure of the system software will also be high, resulting in uneven distribution of output water. Therefore, in specific applications, a certain number of membrane circuit boards are placed in a high-pressure container, and then the high-pressure containers are sorted according to a certain sorting method. According to the steps of pure water and concentrated water flowing into one side respectively, the concentrated water from the first group of water supply and drainage equipment is injected into the next boiler equipment as the first section, and the concentrated water from the first section of water supply and drainage is then flowing into the next high-pressure container as the second section, and so on into other sections. This can correspondingly improve the equipment's yield and reduce the cost of source water.

The above is the "pure water recovery rate of reverse osmosis equipment" shared by Jiajie, hoping to be helpful to you. You can calculate according to the above formula, and the answer obtained is relatively accurate and can be used as a reference.
